<span>Zambia has large copper resources and is one of the world's largest exporters of copper. However, it is very dependent on this resource, and when the price of copper goes down, the economy suffers.</span>
Answer:
Between 2000 and 2012, the Aral Sea has experienced less water income, increased salinity, significant loss of water, the formation of separate parts, and huge loss of biodiversity.
Explanation:
The Aral Sea, once one of the largest in the world, has experienced a tragic story since 2000. Once a great and vibrant lake, it came on the verge of drying out and dissapearing from the map. The reasons for this have been the smaller water income, loss of water, increased salinity, formation of smaller separated lakes, and loss of biodiversity.
Because of agriculture, namely, cotton farming, the water supply to the lake has been significantly lowered, leading to larger evaporation than water income. The lake started to lose its water rapidly, and by becoming shallower its temperature rose, so the evaporation became even larger, the salinity increased, and from one large lake, few smaller ones have formed because a large portion of it dried out. Because of all of the aforementioned things the biodiversity suffered badly.
This causes : Ocean currents
The water movement around the ocean basin was generated from the forces acting upon the water, such as Earth's rotation, wind, temperature, and Earth's Gravitation
Answer:
scale height = 19.80 km
Explanation:
given data
earth scale height = 8.6 km
atmospheric pressure = 10%
to find out
scale height
solution
we know that with the scale height we can find value of physical parameter that is change with height
and height is that value of pressure or density 
th of ground value
so we can say
= 10%
= 0.1
take log both side
t log(0.3678) = log 0.1
t = 2.3025
so
scale height for 10% is
scale height = 2.3025 × 8.6
scale height = 19.80 km
